QuICS Contingent Heads to Premier Quantum Information Conference

January 12, 2018

Research from the Joint Center for Quantum Information and Computer Science (QuICS) will feature in seven talks at the 21st annual Conference on Quantum Information Processing (QIP).

The meeting, which has become a pillar of the quantum information research community over the past two decades, will bring together hundreds of the world’s experts for five days of talks on all things quantum. This year’s event was co-sponsored by QuICS and will be hosted Jan. 15-19 by QUTech at the Delft University of Technology in the Netherlands.

“The breadth of QuICS research being presented at QIP is a testament to the strength of our program and the ongoing scientific leadership of our students, postdocs and faculty,” says Andrew Childs, co-director of QuICS.

Shalev Ben-David, one of two recently arrived QuICS Hartree Postdoctoral Fellows, had a pair of papers accepted to this year’s meeting. He’ll deliver a talk on one, which refines the understanding of a particular way to measure quantum communication complexity—the amount of quantum information two parties must exchange in order to play a mathematical game. It studies the limits of a prior technique for determining the bare minimum amount of information that must be exchanged, and it proves that certain games require much more than that bare minimum.

Penghui Yao, one of last year’s Hartree Fellows, had one talk accepted. That work examines another quantum communication task: trying to simulate a noise-free, interactive quantum communication protocol with a noisy one. “Interactive quantum communication protocols are much more complicated than the non-quantum protocols,” says Yao, adding that noise can create unwanted entanglement between quantum systems. “We design a new mechanism to take care all these quantum noises and reduce the problem to designing noise-resistant non-quantum communication protocols.”

One of the newest QuICS Fellows, Brian Swingle, also had two talks accepted (papers are here and here), both of which continue to probe the importance and utility of entanglement in understanding quantum field theories and the low-energy states of quantum systems. Swingle will miss this year’s conference, though. He’ll be attending the It from Qubit summer school in Bariloche, Argentina, where he will lecture about quantum chaos.

QuICS is a partnership between the University of Maryland and the National Institute of Standards and Technology. It is one of 14 centers and labs in the University of Maryland Institute for Advanced Computer Studies.
